2.4GHz to 2.5GHz 802.11g/b
RF Transceivers with Integrated PA
DC ELECTRICAL CHARACTERISTICS (continued)
(MAX2831 EV kit: V CC_ = 2.7V to 3.6V, V CCPA = V CCTXPA = 2.7V to 4.2V, T A = -40°C to +85°C, Rx set to the maximum gain. CS =
high, RXHP = SCLK = DIN = low, RSSI and clock output buffer are off, no signal at RF inputs, all RF inputs and outputs terminated
into 50 ? , receiver baseband outputs are open. 100mV RMS differential I and Q signals (54Mbps IEEE 802.11g OFDM) applied to I/Q
baseband inputs of transmitter in transmit mode, f REF = 40MHz, and registers set to recommended settings and corresponding test
mode, unless otherwise noted. Typical values are at V CC = 2.8V, V CCPA = 3.3V, and T A = +25°C, LO frequency = 2.437GHz, unless
otherwise noted. RF inputs/outputs specifications are referenced to device pins and do not include 1dB loss from EV kit PCB, balun,
and SMA connectors.) (Note 1)

AC ELECTRICAL CHARACTERISTICS—Rx Mode
(MAX2831 EV kit: V CC_ = 2.8V, V CCPA = V CCTXPA = 3.3V, T A =+25°C, f RF = 2.439GHz, f LO = 2.437GHz; receiver baseband I/Q out-
puts at 112 mV RMS (-19dBV), f REF = 40MHz, SHDN = CS = high, RXTX = SCLK = DIN = low, with power matching for the differential
RF pins using the typical applications and registers set to default settings and corresponding test mode, unless otherwise noted.
Unmodulated single-tone RF input signal is used with specifications which normally apply over the entire operating conditions, unless
otherwise indicated. RF inputs/outputs specifications are referenced to device pins and do not include 1dB loss from EV kit PCB,
balun, and SMA connectors.) (Note 1)
